ADJUSTABLE BEST FOR BEDS.

T 0 all whom it may concern:

Be it known that I, LE0 E. BIER, a citizen of the United States, residing at Corvallis, in the county of Benton and State of Oregon, have invented certain new and useful Improvements in Adjustable Rests for Beds, of which the following is a specification.

This invention embodies a rest designed to be used in hospitals, sick rooms, and other places, in connection with beds, said rest being associated with suitable means for moving the same into different angles of inclination, whereby to correspondingly adjust the position of a patient or person lying on the mattress or equivalent support of the bed.

The construction of the adjustable rest hereinafter described is designed particularly with a view to subserving the simplicity thereof, whereby the device may be produced very cheaply and at the same time is easy to operate, and also adapted to be applied to beds of different sizes.

For a full understanding of the present invention, reference is to be had to the following description and to the accompanying drawings, in which- Figure 1 is a top plan view of the adjustable rest showing the manner of attachment of the same to the rails of a bed, the latter being broken away. Fig. 2 is an end elevation of the rest arranged in operative position on the supporting parts of the bed. Fig. 3 is a side elevation showing the device in its lowermost adjustment, dotted lines illustrating the range of movement in varying the inclination of the rest frame. Fig. 4 is a combined view illustrating one of the guides to which the rest or frame is pivoted. Fig. 5 is a fragmentary view showing more clearly the mounting of the operating shaft.

Throughout the following detail description and on the several figures of the drawings. similar parts are referred to by like reference characters.

In the drawings. 1 denotes the posts usuallv formin a part of bed construction. and 2 the side rails of the bed. Secured in any suitable manner to the side rails 2 are the blocks 3. and the opposite sides of the rest frame 4 are pivoted at the free extremities thereof to said members 3, as shown at 5. The rest frame 4 is of somewhat U- shape. and its sides are connected bv a sectional member 6. the sections of which telescope in the well-known manner.

Attached to the posts 1 by detachable Specification of Letters Patent.

clamps 7 are the vertical guides 8, the upper and lower ends of which are bent rearwardly, as shown most clearly in Fig. 3 of the drawings. Mounted on the guides 8 and connecting the same together, is a cross bar 9, also embodying telescoping sections simi lar to those of the member 6 of the rest frame 4. The cross bar 9 is provided with couplings at its end, through which the guides 8 pass. The lower ends of the guides 8 have mounted thereon hangers provided with bearings for the operating shaft 10, the ends of which are preferably square or otherwise formed to receive the crank handle 11 by which the shaft 10 is adapted to be rotated. The shaft 10 is composed of telescopingsections for the same purpose as are provided the sectional construction of the members 6 and 9, namely, to facilitate the application of the invention to beds of different widths.

On the shaft 10 near its opposite ends are carried the sprocket or similar wheels 12 around which pass the endless chains or belts 18, the latter also passing around the wheels 14 supported upon stub axles 15 carriedbv the upper ends of the guides 8.

Lifting arms 16 are provided and said arms are adapted to slide telescopically in the opposite sides of the rest frame 4. The arms 16 are connected at their outer or free ends with the cross bar 9 and it will therefore be understood that when the shaft 10 is rotated by the handle 11, the bar 9, which is connected, to the chains or belts 13, may be raised and lowered at will by the operator. As the bar 9 is raised, the lifting arms 16 slide outwardly and rearwardly from the sides of the frame 4, as shown most clearly by dotted lines in Fig. 3, the movement of the parts being just the reverse when the bar 9 is lowered. The inclination of the rest frame 4 may therefore be readily adjusted according to the desire of the patient or person using the bed to which the invention is applied.

A flexible support 17 is connected in any substantial way to the sides and connecting member 6 of the rest frame 4 and the mattress of the bed to which the device is secured will rest at one end upon said support 17.

As shown in Fig. 5 of the drawings, the sprocket wheel 12 is formed with a plurality of openings 12 adjacent to its toothed periphery and said openings are adapted to receive a pin 18 also arranged to engage an opening in a flange in one of the bearings in which the shaft 10 is mounted. Cooperation of the parts as above described will be effective to lock the lifting arms 16 at a predetermined adjustment.

Having thus described the invention, what is claimed as new is:

1. In combination with a bed comprising side rails, an adjustable rest consisting of a rest frame pivoted at one end to the side rails, lifting arms slidable longitudinally of the sides of the frame at the free end portion of the latter, and means secured to the bed and connected with said lifting arms for causing sliding movement of the arms in respect to the frame in raising and lowering the latter to correspondingly adjust the position of the frame aforesaid.

2. In combination with a bed comprising side rails, an adjustable rest consisting of a rest frame pivoted at one end to the side rails, lifting arms slidable longitudinally of the sides of the frame at the free end portion of the latter, a cross bar adjacent to the free end of said frame, and connected with the lifting arms aforesaid, and means for raising and lowering said cross bar.

3. In combination with a bed comprising side rails, an adjustable rest consisting of a rest frame pivoted at one end to the side rails, lifting arms slidable longitudinally of the sides of the frame at the free end por tion of the latter, a cross bar adjacent to the free end of said frame, guides upon which said cross bar is adapted to move vertically, a shaft carried by said guides, means connect-ing said shaft with the cross bar, and means for turning the shaft.

4%. In combination, a bed embodying corner posts and side rails, guides detachably secured to said corner posts, a cross bar mounted for vertical movement on said guides, a shaft supported by the guides, Wheels carried by said shaft at the lower ends of the guides and other wheels supported by the guides adjacent to their upper ends, endless members passing around said wheels, means connecting said endless members to the cross bar, a rest frame, and lifting arms carried by the rest frame and secured to the cross bar.

In combination, a bed comprising corner posts and side rails, a rest frame mounted on said side rails and consisting of sides, and a connecting bar composed of telescoping sections, a vertically movable cross bar connected to said rest frame and composed also of telescoping sections, and means for raising and lowering the cross bar for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
